[CentOS-devel] Curating containers

Wed Feb 10 07:29:10 UTC 2016

Hi,

   Vaclav presented the build pipeline very nicely and this would take out
lot of tension for building the code, checking the code standards and test
cases from the developer.

I would like to add few points on this.

In this TDD process all the environments (including the build, test,
delivery) would be created as a container and once the step is over it will
destroy the environment. As output this will generate a application runtime
along with the successfully built application code to registry.

As you mentioned this would be tagged with test along with jenkins build
id, so that developer or QA can trace for which commit this is built.

Then for the next stages, successfully built image would be deployed to
openshift instance to get through the test, delivery stages checking, along
with the quality gates.

all the stages should be linked to pipeline and should be easily
re-producible so that any one can check or regenerate the issues instantly.

Few weeks back I created almost a similar system (without vagrant) and it
was very much welcomed by the developers.

Thanks
